Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides a vibration dehydrator for further dewatering raw materials discharged from a classifier to remove sand, etc. in a gravel pit or a stone crushing plant. Regarding.

(Prior Art) In the past, raw materials discharged from a classifier were transported by truck or the like without being dehydrated.

(Problems to be Solved by the Invention) Generally, a classifier is used to wash and sort sand from undiluted turbid water at a gravel extraction site or a stone crushing site. Since the sand that has been sanded contains a lot of water, when it is transported by truck or the like, it causes inconveniences such as water leaking from the loading platform onto the road.

For example, the classifier B shown in FIG.
2, but the sand that is discharged still contains a lot of water.

(Means for Solving the Problems) An object of the present invention is to further dehydrate the raw material containing moisture discharged from the classifier B as described above.

In order to achieve this object, the present invention provides a conveyor belt that is wound around a driving roller and a driven roller that are hung horizontally on a machine frame, and whose conveying side moves diagonally upward.
This is a vibratory dewatering machine that forms a gutter section that takes over sand containing water discharged from a classifier, and supports this gutter section on a vibrating table equipped with a vibrator. It is installed independently in the atmosphere.

(Example) The illustrated embodiment will be described below.

The vibration dehydrator of the present invention is installed independently in the atmosphere following a classifier, etc.

The rod 19 connected with Seat plates 22, 22 are attached, and springs 23, 23 are interposed between these seat plates 22, 22 and the plate 20 of the vibration table 8, respectively.

These support devices 14, 14 are for preventing the vibration table 8 from falling in the inclination direction, and they elastically support the vibration table 8 with the springs 23, and are provided between the holes 21 of the rods 19. Since there is a margin for this, the vibration of the vibration table is not hindered in any way.

The vibrating table 8 as described above supports the central portion of the belt 6 on the conveyance side, and the belt 6 is curved along the inner surface of the vibrating table 8 to form the gutter section 7 . In order to facilitate the formation of this gutter portion 7, five rows of carrier rollers 24, 24 are arranged on the machine frame 1 on both the front and rear sides of the vibration table 8.

Therefore, the driving roller 2 and the driven roller 3
The belt 6 circulating between the belts 6 is in a flat state on the delivery side, and gradually becomes curved as it moves from the driven roller 3 toward the fifth row carrier roller 24' and the vibration table 8, forming a gutter section 7. and then 5
As it moves from the row carrier roller 24 toward the drive roller 2, it becomes flat again.

Reference numeral 25 denotes a skirt that is attached depending on the condition of the raw material, and is disposed below the gutter section 7 and is in close contact with the inner surface of the gutter section. Skirt 25 is
It is a rubber plate and is made larger than the inner diameter of the gutter part 7, so that the skirt edge slides into contact with the inner surface of the belt 6 that is being transferred, is biased, and is curved in the belt transfer direction. . Further, the upper edge of the skirt 25 is located below the upper edge of the gutter portion.

The skirt presser 29 is attached by connecting the connecting member 31 and the horizontal member 28 with bolt nuts 34, 34, 34, but the horizontal member 28 and the connecting member 31 have elongated holes 35...3 in corresponding positions, respectively.
6... are provided, so that the mounting position of the skirt 25 can be adjusted vertically and horizontally.

In addition, 37 is a drain plate installed at the rear end of the machine frame 1;
Reference numeral 38 indicates a drain plate provided on the lower rear side of the machine frame 1, 41 indicates a water tank, 39 indicates a motor for driving the drive roller 2, and 40 indicates a walkway for use when the vibration dehydrator breaks down.

Next, the operation of the vibrating dehydrator A when the skirt 25 is attached will be explained.

In FIG. 4, turbid water 50 is supplied into a classifier B, and sand that settles to the bottom of the machine due to the difference in specific gravity is transferred by a spiral plate 51 and discharged from a discharge port 52.

And this vibration dehydrator A is the discharge port 5 of the classifier B.
2, and is arranged so that the sand discharged from the discharge port 52 is transferred to the gutter section 7. Further, the belt 6 is circulated by the drive of the motor 39, and the vibration table 8 is vibrated by the rotation of the vibration motors 13, 13. First, when the sand (raw material) discharged from the discharge port 52 of the classifier B is transferred to the gutter section 7, since the gutter section 7 is inclined, if this sand contains a lot of water, the sand will Although the water tries to flow along the gutter 7, it is blocked by the skirt 25 as shown in FIG. The vibration of the vibration table 8 is transmitted to the raw material such as sand via the belt 6, and due to the action of this vibration, the water between the sand particles is expelled, and the expelled water 53 is inside the skirt 25. is stored in

During this time, the belt 6 is moving, and the sand 54, which has a relatively low water content, is transferred to the end of the conveyor, from where it is dumped onto the carry-out conveyor 56 through the chute 55 and placed in a suitable position. transported to.

On the other hand, water 53 stored inside the skirt 25
When the water surface exceeds the upper edge of the skirt, it overflows, flows on the belt 6, and falls from the lower end of the conveyor into the water tank 41.

At this time, since there are draining plates 37 and 38, water will not be scattered in the work area.

The water stored in the water tank 41 is drained to an appropriate location by a pump (not shown).

As described above, the vibration dehydrator A is capable of further dewatering the sand 54 discharged from the classifier B.

The height of the skirt 25 can be adjusted according to the amount of raw material to be processed using the long holes 36 of the skirt holder 29, and if the bolts and nuts 34 are loosened appropriately, the height of the skirt 25 can be adjusted within the range of the long holes 35 of the horizontal member 28. The skirt can move left and right inside, and can follow the meandering of the belt 6 in the left and right direction.

In addition, if the moisture content of the raw material is low, or if the slope of the conveyor is made small even if the moisture content is high, the sand will not flow down the conveyor even if the skirt 25 is not provided, and in this case, the dewatered water will Below the conveyor, sand is conveyed above the conveyor.

Next, a second embodiment will be described.

FIG. 6 is a schematic diagram showing a second embodiment of the vibration dehydrator of the present invention. The feature of this embodiment is that a flexible conveyor belt is used as the conveyor belt, and the structure of various parts is different from the first embodiment, so the differences will be explained in particular.

The flexible conveyor belt 60 circulates between a driving roller 63 and a driven roller 64 as in the first embodiment.

This flexible conveyor belt 60 has a seventh
As shown in FIG. 11, it consists of a bottom belt 61 and side belts 62, 62 integrally formed therewith, and the side belts 62, 62 are bellows-shaped as shown in FIG.

Therefore, the flexible conveyor belt 60
The side belts 62, 62 are shaped like a gutter from the beginning, and the reason why the side belts 62, 62 are bellows-shaped is that they can be wound around the rollers 63, 64.

Therefore, the outer periphery of the bellows of the side belts 62, 62 expands during winding.

Since the belt 60 has a gutter shape from the beginning, the vibration table 8' has a flat shape as long as it can simply support the bottom of the belt 60, and the vibration table 8' has a support plate 9', The plates 20' for the support devices 14, 14 are also shaped accordingly, as shown in FIGS.

Incidentally, reference numerals 65 and 65 are guide portions that stand up along both side edges of the vibration table 8', and
This is to guide you.

66 is a flat carrier roller that supports the bottom of the belt 60, and is also attached to the front of the vibration table 8'.

67, 67, 67 are return side guide rollers attached to the lower side of the machine frame 1, and this return side guide roller 67 is composed of a large roller 68 and a small roller 69, as shown in FIG. , the large roller 68 rotates together with a rotating shaft 71 mounted between bearings 70, 70, and rotates the bottom belt 61.
The small roller 69 is rotatable about the rotating shaft 71 and guides the lower surface of the side belt 62.

Further, 72, 72 are guide rollers for the left and right directions of the belt 60.

Reference numeral 73 denotes a skirt that is supported by the mounting angle 26 similar to the first embodiment, but this skirt 73 has a bottom tongue portion 74 in contact with the bottom belt 61 as shown in FIGS. 12 and 14. It consists of side tongue parts 75, 75 that are in contact with the side belts 62, 62, and the side tongue parts 75, 75 are shaped longer than the bottom tongue part 74. This is because the side belt 62 is bellows-shaped, and thus prevents the raw material from flowing down the skirt through the gap created between the side belt 62 and the side tongue portion 75.

In addition, this skirt 73 is made of one rubber plate,
It is made by cutting out so that a bottom tongue 74 and a side tongue 75 are formed.

In the second embodiment as described above, as in the first embodiment, when the raw material from the classifier B is put into the gutter 7', the vibration table 8' gives vibration to it, and the dehydrated sand is The sand drop chute 76 is formed above the conveyor to distribute water to the bottom of the conveyor, but the sand drop chute 76 is formed in a slightly larger size, and therein is a beader for sieving off sand adhering to the conveyor. 77 are arranged. Beader 77 is the 7th
As shown in the figure, from the motor 78 to the chain 79
The belt 60 is rotated through the belt to vibrate the belt 60 up and down, thereby sieving off sand attached to the belt.

Although only the case where sand is used as the raw material has been described above, the vibration dehydrator of the present invention can also be used when the raw material is relatively large grains such as gravel.

(Effects of the Invention) According to the vibrating dehydrator of the present invention, the raw material containing moisture put into the gutter from the classifier etc. is vibrated by the vibrating table while being conveyed, and this vibration action causes the sand to be removed. The water becomes dense and the water that is between the sand particles is expelled, and the water flows downward over the sand, producing dehydrated sand.
